4:5 Inspect the ultra sonic sensor for the extending-section, where applicable. Make sure
that it is positioned correctly and free from damage.
NOTE: This is optional equipment. It is not standard.
4:6 Verify that the ultra-sonic sensor functions correctly and that it stops the extending-sec-
tion. To do this, follow the procedure below:
1. Operate the hook-lift and tip it up, in tip mode.
2. Operate the extending section and fully retract it (move it inwards). The ultra-
sonic sensor should detect the extending section moving towards it and even-
tually signal for the extending-section to be stopped, approximately 300 mm
from its end point. This ensures that the centre-lock is not activated.
